High speed segmented blades have always been the bread and butter of the diamond tools industry, and the trend doesn't look to change. The majority of segmented blade sales is in the 12"-14" range, but larger diameters have been increasing in popularity. This category of blades is designed for use on high speed demo saws, air saws, and low horse-power walk behind saws, and intended to cut green concrete and asphalt in dry conditions. As with any diamond blade, adding water will increase the life and aid in the cooling of the blade. The PREDATOR (PRD) series is a true mid-range blade in the green concrete/asphalt category. The PREDATOR incorporates a higher quality diamond than the HA5, HA3, or SPL series of blades. The PREDATOR is a good mix between high end performance and affordability.
